In the 1871 Census my gt grandmother Mary Ann Cousins is shown with family in Cuckoo Lane, St Martin as follows:   COSSENS, George     Head            28        1843 COSSENS, Elizabeth   Wife             28        1843 COSSENS, Thomas    Son              9          1862 COSSENS, Hannah     Daughter       7          1864 COSSENS, John         Son              5          1866 COSSENS, Mary AnnDaughter        3          1868 COSSENS, James       Son              9 months          1870   The only reference I can find to her sister Hannah is this census - there does not even appear a birth record.  Similarly I can't find a birth record for her brother James.    Do people think that by this time people were still not registering births?   thanks Megan
